The Rock River Arms LAR-15M Operator ETR is a 5.56x45mm NATO semi-automatic rifle with a 16-inch chrome-lined barrel, two-stage match trigger, and RRA 6-position NSP-2 carbine stock. Aluminum receiver, black finish, 30+1 capacity, weighs 6.40 lbs.

The chrome-lined 16-inch barrel improves corrosion resistance and barrel life, and makes cleanup after high-volume range sessions less tedious. The two-stage match trigger is the notable upgrade here over a standard mil-spec trigger. The first stage takes up slack with light pressure, then the second breaks cleanly, which helps with consistent shot placement. The aluminum receiver keeps weight at 6.40 lbs. An A2 flash hider is fitted at the muzzle. The 6-position stock adjusts for different shooters and shooting positions. Optic-ready upper means no fixed iron sights are included; you run whatever optic or sight system fits your needs.
